My grandfather ask me this puzzle problem.
Three friends were traveling together and one night they made some "littis" and went to sleep without eating any "littis". During the night, one of the friends woke up and divided the "littis" into three equal parts, with one extra "litti" left over. He gave the extra "litti" to the dog and ate his one out of three part and he went back to sleep. After some time, another friend woke up and he also divided the "littis" into three equal parts, with one "litti" left over. He gave the extra "litti" to the dog, ate his one part, and went back to sleep. The third friend woke up and did the same thing. In the morning, all three friends woke up and divided the remaining "littis" into three equal parts, with one left over. They ate their parts, and gave the extra "litti" to the dog. Finally, no "littis" were left. Can you guess how many "littis" there were originally?
"Litti" is a popular traditional food item from the Indian subcontinent, particularly in the eastern states of Bihar, Jharkhand, and Uttar Pradesh. It consists of wheat flour dough balls stuffed with a mixture of roasted gram flour, spices, and sometimes also includes vegetables like onion, garlic, or tomatoes. The littis are then baked over a wood or cow dung cake fire until they become golden brown and crispy on the outside, and soft on the inside. They are typically served with a chokha, which is a dip made of roasted eggplant or potatoes, and sometimes also with tomato or coriander chutney.I have tried bruteforce on number of littis and found the number as sequence of 79,160,241…
Can someone proof how this patterns of number is following ??
